    Description

    WT102 Description

    Overview

    The WT102 is a LoRaWAN smart radiator thermostat for managing heating control systems. It regulates room temperature automatically and manually, and reacts quickly to abnormal temperature differences or extreme cold by adjusting the valve opening.

    Self-Powered, Maintenance-Free

    Thermal energy harvesting powers the WT102 from the temperature difference of the heating circuit, eliminating battery replacement and wired power. When water temperature exceeds 45 °C, the device is powered via the thermoelectric effect.

    Smart Heating Schedules

    One preset date period with up to 16 customizable heating plans enables time-controlled regulation, automating comfort while reducing energy use.

    Comfort & Safety

    Open-window detection, freeze protection and a child-lock feature protect rooms and devices, while theft-deterring accessories add structural anti-theft protection for public areas.

    Easy Setup & Linkage

    NFC enables one-touch configuration, and the WT102 works with the WT401 wireless thermostat for remote linkage control. An external NTC sensor can be connected for accurate ambient sensing.

    Integration

    Compliant with standard LoRaWAN gateways and the Milesight Development Platform, with local storage of 1,000 entries, data retransmission and FUOTA for reliable operation.

    Industry Applications

    WT102 Industrial Applications

    Commercial Buildings

    Offices and common areas automate radiator heating with schedules and open-window detection, cutting energy waste without wiring or battery maintenance.

    Public Facilities

    Schools, hospitals and public spaces benefit from child lock and anti-theft accessories while keeping rooms comfortable and protected from freezing.

    Hospitality & Residential

    Hotels and homes regulate room temperature automatically and manually, with WT401 linkage for room-level comfort control.

    Energy Management

    Self-powered operation and LoRaWAN backhaul make large-scale radiator retrofits simple, feeding heating data into energy-management platforms.
